Apache Hive RBAC Configuration with SQL

Introduction

This guide addresses common Apache Hive Role-Based Access Control (RBAC) configuration with SQL issues, specifically focusing on the challenges encountered when setting up admin roles and permissions with SQL queries. We'll walk through a real-world example of troubleshooting and resolving these issues in a Docker-based Hive environment.

Understanding the Problem

Common Error Messages

When attempting to configure RBAC in Hive with queries like:

SHOW ROLES;
SET ROLE admin;
CREATE ROLE test_role;
GRANT ROLE test_role TO USER tester;

For example, for role creation query you might encounter various error messages depending on your connection method:

JDBC Connection (e.g., DBeaver)

SQL Error [1] [08S01]: org.apache.hive.service.cli.HiveSQLException: Error while processing statement: 
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. 
Current user : root is not allowed to add roles. User has to belong to ADMIN role and have it as current role, for this action.

Hive CLI (e.g. beeline or hive -e)

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. 
Failed to retrieve roles for null: Required field 'principal_name' is unset! 
Struct:GetRoleGrantsForPrincipalRequest(principal_name:null, principal_type:USER)

Root Causes

The issues typically stem from:

1. Incomplete authentication configuration
2. Incorrect authorization provider settings
3. Missing user-to-role mappings
4. Improper service account permissions

Environment Setup for Apache Hive RBAC Configuration with SQL

Prerequisites

Before proceeding, ensure you have:

• Administrative access to your Hive environment
• Ability to modify Hive configuration files
• Access to restart Hive services
• Basic understanding of XML configuration files

Locating Configuration Files

First, locate your Hive configuration file hive-site.xml directory. You can run these commands to check the common locations:

ls /etc/hive/conf/hive-site.xml
ls /etc/hadoop/conf/hive-site.xml
ls /usr/lib/hive/conf/hive-site.xml
ls /opt/hive/conf/hive-site.xml
ls $HIVE_HOME/conf/hive-site.xml

Or run this command to find the correct location:

find / -name "hive-site.xml" 2>/dev/null

File Permission Requirements

Ensure proper file permissions:

ls -l /opt/hive/conf/hive-site.xml
# Should show something like:
# -rw-r--r-- 1 root root 3342 Jan 31 16:04 /opt/hive/conf/hive-site.xml

Step-by-Step Solution for Apache Hive RBAC Configuration with SQL

1. Backup Existing Configuration

Always create a backup before making changes:

cp /opt/hive/conf/hive-site.xml /opt/hive/conf/hive-site.xml.backup

2. Update hive-site.xml

Create a new configuration file with all necessary settings:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <!-- Metastore Connection -->
    <property>
        <name>hive.metastore.uris</name>
        <value>thrift://hive-metastore:9083</value>
    </property>

    <!-- Database Configuration -->
    <property>
        <name>datanucleus.autoCreateSchema</name>
        <value>false</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:postgresql://hive-metastore-postgresql/metastore</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>org.postgresql.Driver</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>hive</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>hive</value>
    </property>

    <!-- Authentication & Authorization Configuration -->
    <property>
        <name>hive.security.authorization.enabled</name>
        <value>true</value>
    </property>
    <property>
        <name>hive.server2.enable.doAs</name>
        <value>false</value>
    </property>
    <property>
        <name>hive.users.in.admin.role</name>
        <value>root</value>
    </property>
    <property>
        <name>hive.server2.authentication</name>
        <value>NONE</value>
    </property>
    <property>
        <name>hive.security.authorization.manager</name>
        <value>org.apache.hadoop.hive.ql.security.authorization.StorageBasedAuthorizationProvider</value>
    </property>
    <property>
        <name>hive.metastore.pre.event.listeners</name>
        <value>org.apache.hadoop.hive.ql.security.authorization.AuthorizationPreEventListener</value>
    </property>
    <property>
        <name>hive.security.metastore.authorization.manager</name>
        <value>org.apache.hadoop.hive.ql.security.authorization.StorageBasedAuthorizationProvider</value>
    </property>
    <property>
        <name>hive.security.authenticator.manager</name>
        <value>org.apache.hadoop.hive.ql.security.HadoopDefaultAuthenticator</value>
    </property>
    <property>
        <name>hive.metastore.execute.setugi</name>
        <value>true</value>
    </property>
</configuration>

3. Restart HiveServer2

# Find hiveserver2 location
which hiveserver2
# Stop the service
hiveserver2 stop
# Wait for complete shutdown
sleep 5
# Start the service
hiveserver2 start
# Wait for startup
sleep 10

Testing and Verification for Apache Hive RBAC Configuration with SQL

1. Verify Service Status

ps aux | grep hiveserver2
netstat -tulpn | grep 10000

2. Test RBAC Configuration

Using DBeaver or another JDBC client/connection:

SHOW ROLES;
SET ROLE admin;
CREATE ROLE user_role;

GRANT ROLE test_role TO USER tester;

Using hive -e/beeline:

Apache Hive RBAC Configuration with SQL Troubleshooting

Common Issues and Solutions

1. Principal Name Null Error If you see:

Required field 'principal_name' is unset!

Solution: Verify the hive.security.authenticator.manager setting is correct and HiveServer2 has been restarted.

2. User Not in Admin Role If you see:

root doesn't belong to role admin

Solution: Check the hive.users.in.admin.role property and ensure it contains your username.

3. Configuration Not Taking Effect

Solution:

• Verify file permissions
• Confirm HiveServer2 restart
• Check logs for startup errors

Advanced Configuration for Apache Hive RBAC

Custom Authentication Providers

For environments requiring custom authentication:

<property>
    <name>hive.security.authenticator.manager</name>
    <value>com.your.custom.AuthenticatorManager</value>
</property>

Multiple Admin Users

To configure multiple admin users:

<property>
    <name>hive.users.in.admin.role</name>
    <value>root,admin1,admin2</value>
</property>

Further Considerations

1. Security Best Practices

   • Regularly rotate passwords
   • Implement proper audit logging
   • Use SSL/TLS for connections

2. Performance Impact

   • Monitor query performance after enabling RBAC
   • Adjust memory settings if needed

3. Maintenance

   • Regular backup of configuration files
   • Document all custom settings
   • Maintain user-role mapping documentation
